Any way to extend the video recording time in Reality Composer Pro from 3:00 to any longer value, such as editing preferences in Terminal or other workaround?
Is there any way to use the strap and a USB-C cable as a live video stream input source that would mirror to Quicktime or some other video capture tool?
I am assuming there is no online documentation or user manual for the strap, but please correct me if I'm wrong. Thank you.
How did we do? We’d love to know your thoughts on this year’s conference. Take the survey here

There is a bug in Unity Plugins: Corehaptics.AssetPickerDrawer throws exceptions and draws incorrectly when fieldInfo or assetType is null (FB17305973). I fixed it and created a pull request: https://github.com/apple/unityplugins/pull/47
It has been months and this bug is really annoying.

Hi, I am having an issue with xcodebuild -showdestinations command.
Steps to reproduce:
Create a new iOS application project in Xcode or use an existing one.
Navigate to this project in a terminal.
Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations
What I expect:
All destinations available in the Xcode UI should be listed.
What I get:
It depends. For new projects, I consistently get only generic platform destinations and my connected physical device.
When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes.
Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably?
Here is a more detailed log and a screenshot:
❯ xcodebuild -workspace 'WorkoutDiary.xcworkspace' -scheme 'WorkoutDiary' -showdestinations

I have developed a Swift macro called @CodableInit in the SwiftCodableMacro module, and I’m able to use it successfully in my main project.
Here’s an example usage:
import SwiftCodableMacro
@CodableInit // This is for Codable macros
public class ErrorMonitoringWebPlugin {
public var identifier: UUID = UUID()
// MARK: - Codable
required public init(from decoder:Decoder) throws {
let values = try decoder.container(keyedBy: CodingKeys.self)
identifier = try values.decode(UUID.self, forKey: .identifier)
}
}
However, when I try to write a unit test for the ErrorMonitoringWebPlugin class, I encounter an issue. Here's the test case:
func testCodableSubjectIdentifierShouldEqualDecodedSubjectIdentifier() {
self.measure {
let encoder = JSONEncoder()
let data = try? encoder.encode(subject)
//Here I am getting this error
Class 'JSONEncoder' requires that 'ErrorMonitoringWebPlugin' conform to 'Encodable'
let decoder = JSONDecoder()
let decodedSubject = try? decoder.decode(ErrorMonitoringWebPlugin.self, from: data!)
XCTAssertEqual(subject.identifier, decodedSubject?.identifier)
}
}
The compiler throws an error saying:
Class 'JSONEncoder' requires that 'ErrorMonitoringWebPlugin' conform to 'Encodable'
Even though the @CodableInit macro is supposed to generate conformance, it seems that this macro-generated code is not visible or active inside the test target.
How can I ensure that the @CodableInit macro (from SwiftCodableMacro) is correctly applied and recognized within the XCTest target of my main project?
I've been messing around with converting my app icons to use Icon Composer. My app has multiple app icons, but I've noticed that I cant seem to set .icon files using the alternate app icon api. I believe this is due to the requirement that alternate app icons live in the Assets Catalogue but .icon files go anywhere in your project. Is there any plan to support this? Or am i missing something?
I was able to successfully set a .icon file for the primary app icon.
I submitted a Feedback (FB17843422) on Monday evening after the keynote about Tahoe beta 1. At the time it still wasn't listed in the "What build does the issue occur on?" dropdown. I selected "I'm not sure" instead hoping I could update it later but as far as I can tell that isn't the case since "Add more information" only lets me add additional comments.
Is there some way for me to do that or is it even necessary?
Weirdness going on here. Our app is crashing on startup with iPad 7s running iOS 18.5. Before updating to iOS 18.5, it was working fine on iPad 7s. Even with iOS 18.5, it is working fine on every device we have tried including dozens of other iPads and iPhones. We have narrowed it down to the SquareReaderSDK. If we remove that SDK, it will launch and work without issues. But, many of our users need the SquareReaderSDK.
The crash happens at app load, before appDelegate didFinishLaunchingWithOptions. So we can't figure out any way to debug the issue. Is anyone else having a similar issue? Square thinks it is an Apple issue.

unable to find developer runtimes in this list https://developer.apple.com/download/all/?q=simulator%20runtime
also, can see it's not being published since iOS 18.2 release, any specific reasons for it? or is the download link changed here?
hey I accidentally deleted my info.plist with holds my app version and other critical things and I don't know how to get it back or how to recode it

It is gone from where I used to find it on Apple’s web site. Is it deprecated or no longer available?
Hi. I have an iPad 7th gen running iPadOS 14.8.1. For testing purposes, I want to upgrade it to the latest release of iPadOS 17, even though the device wants me to upgrade to iPadOS 18.5. Is there a way to upgrade it to iPadOS 17?
btw this would free-up a newer iPad running iPadOS 17 so I can install iPadOS 26 beta.
Thank you.

I would like to inquire about a concern related to the app review process. Specifically, I would like to understand if forcefully denying an application's execution on the iOS Simulator (for instance, by implementing a check in the code that prevents the app from running in a simulated environment) could negatively impact or delay the app’s approval during the App Store review process.
This measure is intended solely for security and integrity reasons during development and distribution. The app functions normally on real devices, and all other guidelines and requirements outlined by Apple are being strictly followed.
Could you please confirm whether such a restriction on the Simulator is acceptable, and if there are any best practices or recommendations from Apple regarding this?
Thank you for your support, and I look forward to your guidance.

I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is:
iOS 18.2 Seed 4
iOS 18.1.1
iOS 17.7.2
An earlier iOS build
I'm not sure
So how to I report this as an iOS 26 beta 1 issue?
In the beta of Icon Composer, I see macOS, iOS, and watchOS icons, but there is nothing about visionOS and tvOS. Those icons are particularly hard and it would be great if this app worked for developing icons for all Apple platforms.
I tried asking this in a WWDC group lab, but they didn't get to it and suggested posting to the forum.
I'm trying to download the iOS 26 restore image for my iPhone 14 Pro Max, which is my test device. However, when I attempted to install it directly via the over-the-air (OTA) update, the iPhone rebooted to the iOS 26 "Welcome" screen, but with no touch functionality—the screen was completely unresponsive.
I restored the device back to iOS 18.5 and tried the OTA update again, but once more, the touch screen stopped working upon completion.
Now, I am trying to download the iOS 26 restore image from the official developer page (https://developer.apple.com/download/#ios-restore-images-ipad-new) to install it manually using my Mac. However, I've run into a problem with the download links:
The link for the iPhone 14 Pro Max (iOS 26) restore image actually downloads the iPhone 14 Pro (iOS 18.5) image.
Conversely, the link for the iPhone 14 Pro seems to provide the correct iPhone 14 Pro Max (iOS 26) image.
The issue is that when I try to restore my iPhone using this seemingly correct file, I receive an error that the firmware file is not valid or compatible. I suspect it's not being properly signed by Apple for my device during the restore process.
Does anyone have the correct, official download link for the iOS 26 restore image for the iPhone 14 Pro Max? How can I fix these errors?
In previous versions of the simulator, it was possible to import files into the Files app by dragging them from the Finder into the Simulator. It appears that in the iOS 26 Simulator, this opens the file in Safari.
I've only tried it with .json files so far.
The documentation at https://developer.apple.com/documentation/xcode/sharing-data-with-simulator says that the original behaviour should happen:
To add files to Simulator, select one or more files in Finder on your Mac, then click the Share button. Select Simulator from the share destination list. Choose the simulated device from the drop-down list. Simulator opens the Files app, and lets you select where to save the files.
I'd love to learn if this is intentional behaviour, and if so, what workarounds there might be. I use this pattern quite a lot, as I have a HealthKit app, and I've built a system that allows me to export workouts as JSON files from a real device, that I can then import into a simulator for testing.
Edit: I found a workaround. Make a folder in Files.app, then search for it within ~/Library/Developer/CoreSimulator/Devices. Open the folder in Finder, then add any files you want to be available in the Simulator.
